| Summary: | The objective of this study was to determine the effects of inoculation of corn seeds with Azospirillum brasilense on grain and fodder production, nutritional value and fermentative characteristics of corn silage. The experimental design was completely randomized and consisted of two treatments with the inoculation of A. brasilense and control. The nutritive value of silages and grain yield were evaluated. The inoculation with A. brasilense did not increase the forage production (P> 0.05) however it resulted in an increase (P <0.05) in the silage material buffer power from pH 4.77 to pH 5.37 (meq HCl/100g MS). In silage the inoculation increased (P<0.05) crude protein, total digestible nutrients and degradability of organic matter. These results are associated with lower (P <0.05) concentration of lignin in the silages inoculated with A. brasilense. The grain yield and plant morphology were not altered (P>0.05) by inoculation. The inoculation with Azospirillum brasilense did not affect the production however it made possible an improvement in the nutritional value of the silage. |
